Continuation of application Serial No. 383,809, filed July 15, 1907.

Specication of Letters Patent.

Patented Dec. 14, 1999. This application filed January 1l, 1909.

Serial No. 471,583.

To all whom it' may concern- Be it known that I, Vieron BLooM, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Sewing-lilachine Structures, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specication.

My invention relates to sewing machine structures and has for its object improved arrangement for permitting the machine parts to be folded together, and the supporting parts to be. folded together to form a compact and neat looking cabinet for containing the folded machine parts, the cabinet requiring only a fraction of the space taken up by the machine structure when unfolded into operative position.

The apparatus described in this application was originally described in my application tiled July 15, 1907, Serial No. 383,809.

In the accompanying drawings which clearly illustrate my invention Figure l is a front elevation of the unfolded structure in position for use; Fig. 2 is a plan view of Fig. l; Fig. 3 is a plan view showing the head in horizontal position; Fig. 4 is a plan view showing the main supporting frame part swung to a position to enable other parts to be folded; Fig. 5 is an enlarged end view taken from the right of Fig'. 3; Fig. 6 is an enlarged front elevation view of the right half of the structure showing the machine head in its folded position; Fig. 7 is a top view of the folded structure with the cover open; Fig. S is an enlarged sectional view taken on plane 8, 8, of Fig. 1; Fig. 9 is a sectional view showing the base of the machine head and its attachment to the machine table; Fig. 10 is a sectional view showing principally the locking arrangement between the supporting sections of the structure; and Fig. 11 is a perspective view of the folded cabinet structure.

The main supporting frame comprises the sections 1 and 2, the section 1 comprising the walls 3 and 4 at right angles with each other, and the section 2 comprising the walls 5 and 6 at right angles to eachother, the sections being rotatable by virtue of hinges 7 connecting the walls 4 and 5, so that the sections may be unfolded to form a rectangular open compartment, as shown in Fig. 1, or a rectangular closed compartment, as shown in Fig. 7. In the open position, as shown in Fig. 1, the walls 4 and 5 are parallel and form the rear wall of the operative machine supporting structure, while the walls 8 and 4 form the side inclosures of this structure. Extending transversely across the top of the wall 3 is a strip 8, to which is hinged a strip 9 by means of hinges 10, this strip 9 being secured to the under side and near the right end of the machine shelf or table 11, the left end of this table resting on top of the wall 6 when the structure is in its open operative position, as shown in Fig. 1.

As' best shown in Figs. 3 and 4, the machine shelf has the opening 12, which in the operative condition of the structure is closed by the base 13 supporting the machine head 14, which may be of any well known construction. The machine parts within the head are driven bythe belt wheel 15 pivoted to the machine head, the belt 16 passing over said wheel and through openings 16 in the base and about the crank wheel 17, which is connected with the pedal frame 18 pivoted to the base 19, secured to the lower ends of the walls 3 and 4 forming the section 1.

As shown in Fig. 1, the pedal frame when in operative position extends into the section 2, but I construct the pedal frame of a stationary right half 20 and the left half 21 pivoted at 22 to the section 20 to be folded against the top of said section to lie wholly within the section 1 and out of the way of other parts during the folding operation.

Referring particularly to Fig. 9, the machine base 13 at its under side is pivoted at its ends to the limbs 23, 24 of a U-shaped frame whose base 25 pivots in a slot 2G cut in the machine table to the rear of the opening 12. lVhen the head is in operative position, as shown in Figs. 1 and 2, the U-frame is in horizontal position with its limbs lying in slots 27 and 28 cut in the machine table 11. Vhen the structure is to be folded into its compact form, the machine head will assume a horizontal position with reference to the table. In this operation the machine head is lifted and swung to the rear with the U-frame, until said frame assumes a vertical position, and the head is then turned over to its horizontal position, as shown in Figs. 3, 4 and 9. Pivoted to the front edge of the machine table ll is a shelf 29, adapted by means of hinges 30 to be swung upwardly and rearwardly to lie against the table 11. Pivoted to the left end of and below the shelf 29 is the extension 31. Also carried by the shelf 29 is a hook frame 32 for supporting the machine head when the table is folded into a final vertical position. Then the structure is to be folded the eX- tension 31 is rst swung in a counter-clockwise direction into position underneath the shelf 29. The machine head is then raised, as before explained, and the shelf with the extension swung over against the table and the hook structure 32 into operative position above the shelf. The machine head is then swung down to its horizontal position adj acent the hook 32. The slot 26 is slightly' longer than the U-frame, so that after the head has been moved to horizontal position, it can be slid to the left and into the hook frame 32. As shown, an escutcheon plate 33 covers the slot 26. After such folding` of the parts supported from the table ll, the frame section 2 is swung rearwardly away from the left end of the table, which can then be dropped into vertical position into the section l, as shown in Fig. 6.

The section 2 accommodates the receptacles 35 and 36, hinged at their edges 37 and 38 to the wall 6. During the folding.

operation these receptacles are swung forwardly against the wall 6 to enable the machine shelf ll to be swung downwardly to its vertical position. After the shelf has been folded to its vertical position, the receptacles are again restored to their original position so that the section 2 can be swung to its folded position to form the containing cabinet shown in Fig. 11. After the sections have been thus folded together, the cover 39 is closed, this cover being hinged to the top edge of wall 6, as best shown in Fig. 4, to form a shelf extension to the table when the parts are in operative position. A shelf 40 can also be provided and pivoted to the right end of table l1. Referring to Fig. 6, this shelf assumes a vertical position when the machine table is uswung to its vertical position, and is then swung downwardly into horizontal position, as shown by the dotted lines. The pivots 41 of the hinges 42, connecting the shelf to the table, are a su'tlicient distance within the edge of the table so that the shelf 40 will lie below the top edges of the sections l and 2, so that the cover 39, when closed, engages these edges.

In Figs. l and 8 I have shown mechanism for supporting the section 2 whenv swung to operative position. Two rods 43 and 44 are pivoted together at their upper ends at- 45,

the rods spreading and their lower ends 46 and 47 being expanded to form supporting feet. A link 48 is pivoted at one end near the lower end of the rod 43 and its other end is pivoted to the f'all 6. A link 49 is pivoted to the rod 44 near its lower end and its other end is also pivoted to the wall t3. rFhe upper ends of the rods 43 and 44 are pivoted to the arm 50 of a bell crank lever pivoted at its elbow 5l to the wall G. `When the structure is to be folded, the other arm 5l of the bell crank lever is swung inwardly and thereby raises the arm 50 and with it the rods 43 and 44, and by virtue of the links 48 and 49 the rods 43 and 44 during their upward movement are also moved toward each other, the result being that the rods are moved entirely within the edges of the wall G, as shown by dotted lines in Fig. 8. When the structure is unfolded to its open, operative position, the arm 5l is raised to a horizontal position, as shown .in Fig. 8, and the rods 43, 44 move downwardly and separate so that their foot ends 46 and 47 will be on a level with the foot blocks 52 secured to the under side of base 19 of section l. To hold the arm 5l in its horizontal position, a shelf 53 is secured near the front and upper edge of the wall G, the arm 5l being slid about and to the top of said shelf and held in position thereon by a spring 54, as best shown in Fig. l. During the folding operation the arm l is moved slightly to the right to clear the shelf 53 and is then swung down to the dotted position shown.

ln Figs. l and 6 are shown locking means for locking the frame parts together after folding. Rod 55 slides in guides 5G, 5T extending from the wall 3 and this rod carries slotted locking plates 58 for engaging with screws 59 extending from the inner face of wall G. The rod 55 at its upper end passes through the block 8, having spring pocket 6l containing a spring G2, which encircles the rod and abuts against the rounded head 63 thereof and this spring tending to hold the rod in an uplposition to hold the locking plates 58 out of locking position. When the cover 39 is closed it strikes the head G3, and the rod 55 is pushed downwardly and the plates 58 hooked over the screws 59 to lock the sections l and 2 together. The lifting of the cover then automatically causes unlocking of these sections. rlhe various walls, which when folded form the inclosing cabinet, can of course be suitably paneled and ornamented, the cabinet being of very neat appearance and requiring very little space. .Vhen it is desired to use the machine parts, the various elements can be quickly unfolded to assume their operative positions and can as readily. be refolded.
